　　Yan Chenggang, a 37-year-old professor at Hangzhou Dianzi University, focuses on intelligent information processing. The algorithm designed by him can detect bad video information in the network and get large-scale application. He often said that scientific research shares worries for the country, and innovation benefits the people. He encouraged students to choose their scientific research direction according to their own plans and interests, and do more research that solves practical problems and is closely related to public life.

　　

　　In the intelligent information processing laboratory of Hangzhou Dianzi University, with the sound of keyboard tapping, a string of codes jumped on the computer screen.

　　Yan Chenggang, a professor and doctoral supervisor at the School of Automation, Hangzhou Dianzi University, is writing the code. Yan Chenggang is 37 years old and has served as the director of the intelligent information processing laboratory. Since 2008, Yan Chenggang, as the second finisher, has participated in the project "Theory and Method of Qualcomm Calculation of Internet Video Streams". The algorithm designed by him can detect bad video information in the network and effectively deal with complex video scenes. Now, this achievement has been widely used.

　　Upgrade algorithm to identify network video and image information.

　　"Now there are a large number of users uploading data to the platform every day, most of which are pictures and video data, which may contain some vulgar content." Yan Chenggang said that this phenomenon has attracted the attention of him and his team.

　　Yan Chenggang said that the traditional filtering algorithm mainly focuses on some fixed features in single-mode content, which can play a certain role when the media form is relatively single, but it is difficult to meet the actual needs at present. So, how to innovate algorithms to complete complex information screening?

　　"We first try to make the algorithm understand the general idea of the whole multimodal content and give a qualitative judgment." Yan Chenggang introduced, but the actual application scenario is very complicated, and it is difficult to meet the actual application requirements by simply giving judgments. Therefore, the team further tried to make the algorithm identify various details in multimodal content, and then connected the details in series to realize the descriptive understanding of multimodal content.

　　With the help of cross-modal retrieval technology, the team transformed pictures and video data into specific words, and on this basis, built a corpus retrieval database for secondary association and reasoning, so as to obtain more accurate semantic information.

　　"When the content is complex and it is difficult to give a detailed and comprehensive description directly, you can find the closest content in the database through retrieval, thus indirectly realizing understanding. In this way, as long as our database is good enough and large enough, we can solve this problem. " He added, "For example, if you enter a Chinese character’ Ma’, the understanding of the content is to draw a horse, while the search only requires finding a horse, which is obviously simpler and time-saving." Focusing on single-mode information processing methods such as images and texts, Yan Chenggang’s team has made many breakthroughs in content saliency detection, complex text recognition, target detection and target retrieval.

　　Innovate to tackle key problems and solve practical problems through scientific research.

　　Distinguished professor of Changjiang Scholar Award Program, young scholars of Changjiang Scholar Award Program, outstanding scientific and technological worker of Chinese Institute of Electronics, winner of Zhejiang Outstanding Youth Fund … Yan Chenggang has won many honors, but he prefers to call himself "information screener". In his view, the goal of team members is to screen out bad information and clear up cyberspace.

　　In the interview, Yan Chenggang always talked about "scientific research sharing worries for the country, innovation benefiting the people". "Do scientific research to indomitable spirit, researchers should have the spirit of responsibility. On the one hand, we must really solve practical problems for the country. On the other hand, we must serve the people. " Yan Chenggang said.

　　Yan Chenggang’s team has successively won the first prize of Science and Technology Award of China Institute of Electronics, the second prize of National Natural Science Award and the first prize of Wu Wenjun Artificial Intelligence Science and Technology Progress Award … Behind the high yield of research results, it is inseparable from his self-discipline and diligence.

　　In 2019, Yan Chenggang followed up an important project in Beijing. It happened that another national key project that the team was responsible for entered a critical stage. How to balance the two projects? Yan Chenggang recalled: "I concentrate on doing projects in Beijing during the day, and the time after 9 pm belongs to team projects. I try my best to solve and demonstrate the problems raised by members during the day." Yan Chenggang said that every Sunday, he would fly back to Hangzhou early in the morning to discuss and study with his team members, and then fly back to Beijing that evening. "That time was simply too busy. Time waits for no one, and opportunity waits for no one. I can’t delay the research progress because of me. I would rather sleep less and make the project progress faster. "

　　Teach by example and support students to explore areas of interest.

　　In the summer of 2021, a news that "using gait algorithm to optimize identity recognition to help criminal investigation solve cases" attracted attention, and the algorithm can play an active role in finding lost children and other fields.

　　"This is the scientific research achievement of the doctoral students I directed. The paper was published at an international academic conference and won the best paper nomination award." Yan Chenggang’s words are full of pride. The practical application of students’ academic achievements makes him very happy: "It is meaningful to combine academic research with public life."

　　Yan Chenggang’s laboratory research scope includes image processing, computer vision, computer graphics, medical image processing, biological information processing and many other aspects. "The research field of the laboratory is relatively broad, and it is also to provide students with more room to play. As long as students are interested in and have potential fields, I support them to explore." Yan Chenggang said that students should be encouraged to choose their research direction and work direction according to their own plans and interests.

　　Meng Xiangsong, a graduate student majoring in control engineering in Tsinghua University, is a student of Yan Chenggang at the undergraduate stage. "I used to send emails to ask Teacher Yan. When he replied, it was often one or two o’clock in the middle of the night. Every time I wrote back, I made a detailed problem analysis and was never vague. " Thanks to Yan Chenggang’s example, Meng Xiangsong has developed good research habits and is currently committed to the research direction of artificial intelligence.

　　Yan Chenggang said: "University teachers must first teach and educate people, preach and teach. This is what Academician Dai Qionghai, my postdoctoral co-tutor, said to me, and it has also become my lifelong pursuit. " He said that he should pass on this spirit of being willing to be a ladder and cultivate more useful talents for the country.

　　CCTV News:This morning, the successful first flight of a new generation of domestic medium-sized helicopter AC352 marked a new breakthrough in China’s aviation industry and high-end manufacturing. CCTV reporters also directly hit the performance of AC352 after its launch.

　　CCTV reporter Wu Jie:The domestic new generation of medium-sized multi-purpose AC352 slowly lifted off the ground and then hovered in the air steadily, which was its first test flight and a key step in the whole development process. The helicopter’s fuselage is very spacious, the widest part is more than two meters, and it can carry up to 14-16 passengers at a time.

　　The advanced integrated avionics system is adopted in the AC352, which can reduce a lot of burden for the pilot during the flight and make him concentrate more on the flight action. We see that it is now rotating around the nose, which shows good flight performance. The AC325 is also the best in riding comfort and the most maneuverable in driving among helicopters of the same class in the world.

　　In addition to testing flight movements, doing some high-speed passing is also one of the necessary test contents for the first flight.

　　Now we see that the AC352 has landed slowly, the whole first flight has been successfully completed, and it is slowly taxiing towards us. So at this special moment of the 60th anniversary of the establishment of the helicopter industry in China, we are also very proud to witness a brand-new achievement of the aviation industry in China.

　　How to repair AC352 both internally and externally

　　As a new achievement of China’s high-end manufacturing industry, AC352 can be said to be both talented and attractive, handsome and fashionable in appearance, and its interior always embodies the people-oriented design concept. Our reporter also paid a close visit to this world-class medium-sized helicopter before the first flight to see how AC352 can be repaired both inside and outside.

　　It is easy to use in flight driving and comfortable and safe for passengers. The spacious fuselage of AC352 makes the ride conditions inside not bad compared with those of high-end commercial vehicles. The specially designed low rotor makes the internal noise level 4 decibels lower than the airworthiness standard, and the huge porthole makes the scenery in the air unobstructed, which is the leading design in similar helicopters. In terms of details, AC352 is the ultimate pursuit of safety.

　　Lu Weijian, Chief Designer of AVIC AC352 Helicopter:The door of the helicopter is 1.4 meters wide, and people can get down soon. In case of emergency, it is convenient to evacuate.

　　Even in the event of an extreme crash, the AC352 will reduce the injury caused by the accident through the linkage of the landing gear fuselage seat.

　　Lu Weijian, Chief Designer of AVIC AC352 Helicopter:How much energy should the landing gear absorb, how much energy should the body structure absorb, and how much energy should the seat absorb? It is normal for the driver, and I can bear that energy, so I can ensure safety.

　　Reporter:This concept is somewhat similar to the anti-collision design of our car.

　　Lu Weijian, Chief Designer of AVIC AC352 Helicopter:Right, that’s right, which means it’s very safe.

　　At the same time, we found that when preparing for the first flight, the top cabin of AC352 can be completely opened, and the engine and complex transmission mechanism inside are completely exposed, which also makes it very convenient for aircraft maintenance personnel to work.

　　Luan Yuqing, deputy stationmaster of AVIC Hafei Flight Test Station:There was no such push-pull design of engine compartment before, so it would be more complicated to open the covers of various overhauls when we were overhauling. With this design now, it will be much easier for us to get to work after the whole opening.

　　Pilots fly easily, passengers sit comfortably, and ground maintenance staff work conveniently. This is the best embodiment of the people-oriented concept of China helicopter design and manufacturing on AC352, and it is also the place that designers are most proud of.

　　Lu Weijian, Chief Designer of AVIC AC352 Helicopter:Finally, the plane will be given to them, and I will satisfy them. Everyone who sits on it tells you that I am comfortable, without vibration or noise. That’s really nice. It can meet the needs of society and provide public services to society. That’s the final evaluation.

　　China and France jointly aim at the gap in the world helicopter market

　　As a helicopter jointly developed by China and Europe, the research and development road of AC352 is also full of legends. In the development of this type of helicopter, China’s aviation industry has completed the introduction and learning from abroad to equal cooperation, and it has completed the gap with the western helicopter industry for decades in just 12 years.

　　At the beginning of the 21st century, China has just completed the introduction of the 5-ton helicopter Zhi 9. At that time, the aviation people in China were thinking about where the civilian helicopters in China should go next. Although some helicopter models developed by international cooperation are advancing, in the eyes of Lu, the current chief designer of AC352, there is a difficulty that must be broken through.

　　Lu Weijian, Chief Designer of AVIC AC352 Helicopter:What is the so-called difficulty? It’s how we build a better plane. We have been thinking about what our users think and what the market needs. This is important, and this is our most difficult.

　　Thus, in 2002, a market survey for a new generation of civil helicopters began, which may be the first time that the developers of China helicopter considered who will use the aircraft and what kind of demand it needs to meet completely before the design of a helicopter.

　　Yang Guangchao, Director of AVIC AC352 Helicopter Project:We have found that in the future helicopter market in the world, some people say that this medium-sized helicopter is called super-medium-sized helicopter, and the market potential of this helicopter is very great.

　　At this time, the European helicopter developers on the other side of the ocean also reached the same conclusion, so a cooperation across the eastern and western hemispheres began. Although in the 1980s, China developed the famous multi-purpose helicopter Zhi -9 through international cooperation, at that time, it was more about introducing technology and learning from each other’s successful experience. This time, researchers from China and Europe will share the technical problems in the development according to the ratio of half to half. Moreover, at that time, everyone’s goal was to develop the best 7-ton civil helicopter in the world.

Lu Weijian, Chief Designer of AC352 Helicopter of AVIC:Let’s decide what is the goal of the product, what are the specific indicators, and what tasks can be performed? Also want to design together. Therefore, the preliminary design was carried out in Marseille, and the technical requirements of the whole machine were determined. After the technical scheme, it took another year to go back to their respective offices to carry out detailed design.

　　Yang Guangchao, Director of AVIC AC352 Helicopter Project:In 2004, China and France signed a framework agreement on the joint development of advanced medium-sized multi-purpose helicopters. Then in 2005, China and France signed a cooperation contract for the joint development of medium-sized multi-purpose helicopters. In January 2006, China and France officially launched the joint development of this AC352 helicopter.

　　Close to customer needs, easy to maintain and lower fuel consumption.

　　How to measure the capability of a helicopter? Designers tell us that apart from flight performance, the most difficult thing for AC352 is to consider the needs of helicopter users in its design. Compared with the progress of technology, the change of design and manufacturing concept of AC352 has left a valuable wealth for China’s civil helicopter industry.

　　Before AC352, civil helicopters in China were basically born out of military helicopters. To design a good civil helicopter, we must always think about future users. Chief designer Lu said that pilots, passengers, and even later crew members, as long as they use this plane, their feelings should be carefully designed, which is a great difficulty in developing AC352.

　　Lu Weijian, Chief Designer of AVIC AC352 Helicopter:After going up and sitting down, different drivers can adjust the height of the seat up and down, that is to say, sitting down, and then he touches each switch, and you can easily operate it in place.

　　Reporter:Well, how do we do this in the design to make the pilot sit comfortably?

　　Lu Weijian, Chief Designer of AVIC AC352 Helicopter:My design distance is designed according to the specified driver’s height to achieve this point. I will use this on the electronic prototype during 3D design and project design to test this and meet this requirement.

　　The maintenance workload is very low, and the time for the plane to leave again will be greatly accelerated, just like when you take a flight, for example, the plane will land, and I can leave in half an hour, which is more convenient for passengers, right?

　　Meticulous design, but also with the production of Excellence to achieve. In order to make it convenient for future users and meet the design requirements, the doors of AC352 can be interchanged, that is to say, if the doors are broken, users can buy and install them themselves just like fitting parts for cars. Compared with the automobile industry, which has a production scale of tens of thousands of vehicles, the production scale of aviation manufacturing industry is much smaller, and it is difficult to achieve parts exchange.

　　It is in this determination that AC352 is also changing the face of civil helicopter production in China: domestic engines are used to realize the "China Heart" for China helicopters, while fuel consumption is lower and maintenance is easier; Equipped with advanced avionics system, pilots can even land automatically at the touch of a button like automatic parking. These previously unimaginable functions have been realized on this helicopter which embodies the painstaking efforts of China aviation people.

　　Lu Weijian, Chief Designer of AVIC AC352 Helicopter:For more than ten years, there has been a painful and happy enjoyment process, because we have entered the aviation industry, which is what we have to bear. The first flight is just a node in my whole research and development process, a node that everyone pays attention to. But I am more concerned about when I can go to the market, how I can meet the requirements of users, provide public service products for the society, and make our due contribution to promoting the development of production economy.

1905 movie network news On January 12th, a premiere ceremony was held in Beijing. The director, together with the leading actors,,, and Luna, attended the premiere ceremony. Together with the big coffee makers and ordinary audience attending the premiere ceremony, they enjoyed the drama as the Year of the Tiger approached and the Spring Festival was celebrated. After the movie, the masters opened their hearts to share their creative feelings, and the guests and audience at the scene counted the feelings and gains during the movie. Well-known directors praised the film with three "particularly good" films, and film critics commented that "Northeast Tiger" is a very gentle film, not only relaxed and happy, but also endless tenderness. "

Just as the theme of the premiere "Tiger in Heart" shows, under the black humor shell, the film contains great realistic thrust, which makes people laugh absurdly and taste the true taste of life. The road of life is bumpy, and it is normal to look for hope in frustration. The film "Northeast Tiger" will be released nationwide on January 14th. I believe this "fierce and absurd" masterpiece will surely bring inspiration and courage to deal with life to the audience who enter the cinema.

　

Geng Jun, the director of "Tiger in the End" in Zhang Yu’s Mary play, was praised as "having great wisdom"

The film "Northeast Tiger" tells the story of Xu Dong and Meiling, a couple who suffered from a middle-aged crisis, laughing at the "big robbery in life", struggling with the absurd world and looking for a way out. The love, hate, obsession and revenge of the little people, in Hegang, the "end of the universe" in the world of ice and snow, bloom with gorgeous fireworks and touching poetry, showing the indomitable and tenacious vitality of ordinary people.

At the premiere, director Geng Jun and starring Zhang Yu and Mary recalled the creative process and chatted with the audience. Referring to the reason why the film was named "Northeast Tiger", Geng Jun explained that he had observed the Northeast Tiger in the zoo, and he was very curious. As the king of the forest, did they want to go out when they were trapped in the zoo? Just as the protagonists in the movie are in trouble, can they be brave in trouble? Therefore, the Northeast Tiger and the hero in the movie are a mutual reflection.

Zhang Yu recalled the filming process and admitted that there was a lot of pressure when shooting, for fear that he would not get into it. However, director Geng Junyong used his humor and wisdom to make him have this "relaxed+happy" experience. Talking about the first cooperation with Mary, Zhang Yu praised "Mary is an actor who can’ fight’ especially, and the cooperation is pleasing to the eye, smooth and smooth." Talking about the cooperation with Geng Jun, Mary bluntly said that he was moved by the director’s "truth". "He is a very intelligent person. I am lucky to join such a team. This film is extremely important to me." For the ending of the cute pet "Ruyi" that the audience cares about, the director intimately comforted everyone that "no animal was injured in the filming."

　

Director Gao Qunshu praised three "particularly good" Yan Feizan "Northeast Tiger" and "Hegang Light"

At the premiere ceremony, many peers in the industry were also attracted by the good reputation revealed in the early stage of "Northeast Tiger", and they all showed up to watch movies and enjoy excellent works. All of them were praised by the success of "Northeast Tiger" and gave high praise to the film. Director Gao Qunshu praised "The Northeast Tiger" as a very wonderful film. Every actor performed it very well, and every shot was particularly liked. Including these gods, these bad tastes were particularly good. " Director Yan Fei said, "The film tells the confusion of a northeast city, but in fact it turns out to be full of goodwill, understanding and understanding between people. Great, the light of Hegang! " Peng Damo was impressed by the humorous interpretation of the film. "The whole work is very good, very textured, and some obstacles in life are interpreted in a particularly humorous way."　

Director Zhang Luan mentioned that he saw a lot of "philosophy and speculation" and incarnated as "tap water" to recommend movies to friends around him. Guan Yue, an actor, smiled and said that he wanted to discuss the details with Mary in private. Shi Hang, a film critic, said, "This is a very gentle film, not only relaxed and happy, but also endless tenderness. I like it very much." The audience also spoke enthusiastically, expressed their feelings and expressed their love for the film. At the end of the premiere ceremony, the leading actors took a group photo as a souvenir and wished the audience a prosperous and powerful year of the tiger.

Appoint civil servants by setting up their own positions in violation of regulations, and engage in sex trading and money trading with many women.

　Gao Yongchang, who has been in charge of the Public Security Bureau of Gui ‘an New District for six years, was investigated on June 13th this year. On December 3, the Provincial Supervision Committee of the Guizhou Provincial Commission for Discipline Inspection informed that Gao Yongchang, a member of the former party group of the Gui’ an New District Management Committee and the former party secretary and director of the Gui’ an New District Public Security Bureau, seriously violated the law and gave Gao Yongchang expulsion from the party; The provincial supervisory Committee gave him the punishment of dismissal from public office; Recover their illegal income; Transfer the suspected crime to the procuratorate for review and prosecution according to law.

According to this circular, it is rare for Gao Yongchang to violate the law and discipline.

The report said: "After investigation, Gao Yongchang violated political discipline and rules, engaged in group gangs and gangs, undermined the political ecology of the Public Security Bureau of Gui’ an New District, lacked political beliefs, rumored rumors, opposed organizational censorship, and failed to report personal major matters in accordance with relevant regulations;

Violation of the spirit of the eight central regulations, formalism and bureaucracy, poor implementation of the work of eliminating evils, packaging materials to cope with superior inspections, illegal acceptance of gifts and gifts that may affect the fair execution of official duties, and illegal use of offices beyond the standard;

Violation of organizational discipline, illegal provision of help for others’ job transfer and job promotion, illegal appointment of civil servants in their own positions, and illegal arrangement of close in-laws to serve;

Violating the discipline of honesty, engaging in power and money transactions with many women, engaging in business activities in violation of regulations, and borrowing and lending from management clients in violation of regulations and making profits;

Violation of mass discipline, playing privilege, shaking power and prestige, damaging the relationship between the party and the masses, and apportioning expenses to relevant construction enterprises in violation of regulations;

Violation of life discipline and long-term improper sexual relations with others.

Violation of national laws and regulations constitutes a duty violation. Taking advantage of his position to seek benefits for others, asking for and illegally accepting other people’s property, the amount is extremely huge, and he is suspected of accepting bribes. "

He was appointed as the first public security director of Gui ‘an New District and was highly anticipated.

Gao Yongchang, a Hui nationality, was born in July 1961 in Lai ‘an County, Anhui Province. After graduating from Southwest University of Political Science and Law with a major in law in 1985, he entered the police field in Guizhou. He has been a policeman for 34 years and is an old public security officer.

Gao Yongchang’s working experience is relatively simple. He spent the first 28 years in guizhou public security and the last 6 years in charge of Gui ‘an New District Public Security Bureau.

After graduating from western politics, he joined guizhou public security. After working as a scout for 15 years at the grass-roots level, he was promoted to deputy director of guizhou public security office (command center), and then served as director and deputy director of the anti-terrorism department of the provincial public security department, director and deputy director of the command center (office).

On February 28, 2013, the Guizhou Provincial Organizing Office approved the establishment of the Gui ‘an New District Public Security Bureau to exercise the law enforcement authority of the municipal (state) public security organs. Gao Yongchang was appointed as the first party secretary and director of the Public Security Bureau of Gui ‘an New District, and was highly anticipated. In January of the following year, Gui ‘an New District was established, and Gao Yongchang became a member of the party group of Guizhou Gui ‘an New District Management Committee at the end of the year.

As the eighth national new district, Gui ‘an New District has taken the leading role in the development of Guizhou’s new economy. The planned control area of the new district is 1,795 square kilometers, involving 21 townships in four cities (districts) under the jurisdiction of Guiyang and Anshun, with a population of 1 million.　

Gui ‘an New District started from scratch with a blank sheet of paper. Under the background of large-scale development and construction, there are frequent economic and social activities and a large floating population. Economic development and social stability cannot be separated from the escort of grassroots social governance. As the first public security director of Gui ‘an New District, Gao Yongchang made great contributions in defending the construction of the new district at the beginning of his duties and won praise from the local media.

Gao Yongchang said in an interview that Gui ‘an Public Security started from scratch, and achieved a breakthrough from scratch in terms of team, organization, equipment and working mechanism. The "hard bones" and "intestinal obstruction" encountered in the process of maintaining stability in the construction of the new district are all rushed to the front line by the new district public security bureau. Every large-scale project and industrial park are completed and every road is successfully opened to traffic, leaving behind the fighting figure and sweat of the police officers in the new district. More than 270 mass incidents of a certain scale have been properly handled, and all of them have been actively and steadily, and there has been no incident that has formed a scale and caused harm.

With the remarkable achievements in the development and construction of Gui ‘an New District, Gao Yongchang, who performed the duty of maintaining and ensuring the social stability of the new district, embarked on the road of corruption and fell to his post six years later.

Two long-term evil gangs were destroyed on the day when the central supervision team was stationed.

Gao Yongchang was informed that there was a problem of violation of law and discipline, such as "less action to eliminate evils and poor implementation, and packaging materials to cope with superior inspection".

Two months before Gao Yongchang’s fall, the 19th Central Supervision Team stationed in Gui ‘an New District, and Gao Yongchang directed and implemented the network-closing operation to crack down on "routine loans".

Huaxi University Town, located in the southeast of Gui ‘an New District, has nine colleges and universities with 150,000 teachers and students. In recent years, college students have been repeatedly infringed by "routine loans". At the end of 2018, Xiaolong (pseudonym), a 2016 student in University Town, reported to guizhou public security that he had been set up by criminals and owed 160,000 yuan in debt within two months. He was threatened to drop out of school if he failed to pay the debt. After investigation, the police found that there were seven students in Huaxi University Town who were forced to drop out of school because of the "routine loan" implemented by this criminal gang, and the highest debt among them exceeded 500,000 yuan.

According to Guiyang Daily, since 2018, the Public Security Bureau of Gui ‘an New District has received reports that college students in its jurisdiction have been forced to pay high repayment by borrowing usury.

On April 20 this year, the 19th Supervision Team of the Central Committee for Eliminating Evil was stationed in Gui ‘an New District. On the same day, the Public Security Bureau of Gui ‘an New District organized a new round of centralized network-closing operations. Under the command of Gao Yongchang, the police of the task force quickly assembled according to the action plan to carry out the arrest operation, and destroyed two evil criminal groups in one fell swoop within two days, and arrested 12 major criminal suspects of the group.　　

One of the two evil criminal groups is the "routine loan" evil gang headed by Yang, which takes college students as the object of infringement, lends money to students, and uses soft violence, illegal detention, threats, intimidation and other means to collect debts. Another gang involved in black gangs, Liu Moumou, has been carrying out illegal crimes such as blocking work and blocking roads, seizing projects, gathering people to fight, intentionally hurting, seeking trouble, teasing and insulting women in Gaofeng Town, Gui ‘an New District since 2013, and has been oppressing the people for a long time, running rampant in villages and doing evil.　　

At that time, the media reported that in less than two days, the two centralized network-closing operations had great momentum and fruitful results, which greatly shocked the crime.

Since the supervision and rectification, Gui ‘an New District has carried out a special campaign to eliminate evils and crack down on new crimes such as "campus loans" and "routine loans". Since July this year, the number of criminal cases in the university town and its surrounding areas has dropped significantly, and the cases of "campus loan", "routine loan" and "two robberies" have been effectively curbed.　

Three months after Gao Yongchang was investigated, on September 23, Gui ‘an New District held the third meeting of the leading group for the rectification of the special struggle against evil in 2019, and allowed pornography, gambling, drugs and evil forces to go unchecked, dereliction of duty and even connivance, and acted as a special rectification promotion meeting for the "umbrella" issue, and arranged and deployed related work.

On November 3rd, the 19th Supervision Team of the Central Committee for Eliminating Evil came to Huaxi University Town to have a discussion and exchange with more than 10 university leaders, teachers and students. Han Hui, secretary of the Party Committee of Guizhou Normal University, said, "Since the launch of the special struggle against evil, especially since the supervision in April, the sense of security of teachers and students in the school has been greatly improved. What everyone is most concerned about is how to establish a long-term mechanism to make the sense of security last."

Two subordinates fell, and one of them acted as an "umbrella" for evil forces.

After Gao Yongchang’s fall, his two subordinates were investigated successively.

　On August 6th, Huang Minggui, deputy commander (presiding) of the Third Brigade of the Criminal Investigation Detachment of the Public Security Bureau of Gui ‘an New District, was investigated. The Commission for Discipline Inspection and Supervision of Gui ‘an New District informed that Huang Minggui was suspected of serious violation of discipline and law, acting as a "protective umbrella" for evil forces, and was currently under disciplinary review and supervision investigation by the Commission for Discipline Inspection and Supervision of Gui ‘an New District. Huang Minggui was transferred to the Public Security Bureau of Gui ‘an New District in December 2013. In July 2016, he served as the deputy captain of the third brigade of the criminal investigation detachment (presiding).

On October 12, the Discipline Inspection and Supervision Working Committee of Gui ‘an New District informed that Xiao Wanlong, the detachment leader of the traffic police detachment of Gui ‘an New District Public Security Bureau, was suspected of serious violation of the law and was under investigation. Xiao Wanlong was appointed as the temporary head of the traffic police detachment of Gui ‘an New District Public Security Bureau after the establishment of Gui ‘an New District Public Security Bureau in 2013. In September 2015, he was appointed as the detachment leader of the traffic police detachment of the Public Security Bureau of Gui ‘an New District.

The hot weather has been going on all over the country for many days. Such heat, even if you just stand still in the sun, will soon break out in a sweat. But there are still many people who stick to their jobs at high temperatures. Protect the safety, traffic, communication, sanitation and greening of the city … Thanks to them, let our life be as usual.

　　

This year, Project ONE, the 50th anniversary model of AMG, received high attention. There are two main reasons: first, it is expensive, and only 275 sets are limited to production, and the price is 2.27 million euros.

Secondly, the data is too strong. This car is equipped with F1 racing car that should only appear on the track. It will be more than 1014 horsepower, and the acceleration of 100 kilometers will take 2 seconds, while the acceleration of 0 to 200 kilometers will only take 6 seconds. What’s even more incredible is that this car is only 1.6 liters, with four motors.

　　

So the question is, how does this sports car make the power so strong?

First of all, the power system of AMG Project ONE is a hybrid system consisting of a 1.6T V6 and four motors. This one originated from the F1 Championship for the 2015 season. Lewis hamilton also won the championship this year with this excellent performance.

According to the published data, 1.6T booster plus 4 motors, the total reached 746kW. One of the four motors provides pumping power for the turbine, which is 90kW. This motor does not participate in direct work to drive the whole vehicle, but provides power source for the electronic turbine. The other three motors are 120kW, which can directly provide power for the whole vehicle. This hybrid mode is a parallel mode.

　　

The advantage of parallel mode is that the energy loss is small, and each motor can drive the whole vehicle independently. In addition to transmission loss and system error, the sum can be calculated by superposition. This power system is about 746kW, minus the superposition of three motors of 360kW, so this 1.6 liter will reach 386kW.

Is it ridiculous? This is something that you can’t even think about. Generally, it takes more than 4L to achieve 386kW, but it can be achieved on a 1.6L platform, just like a 3-year-old child lifting a weight of 80kg.

The maximum NA of conventional 1.6L is only about 90kW, and the rotating speed is 6000rpm. If the rotating speed is doubled to 12000rpm, the times of doing work per unit time will be doubled. Plus, if it is increased by 40%, it will reach 252kW.

　　

So how did this model achieve 386Kw? This AMG with a F1 heart not only uses exhaust gas to drive the turbine to increase the intake density, but also uses a 90kW motor to drive the electric turbine to increase the intake density, so it is entirely possible to reach 386kW.

This is the secret weapon of Super Engine with super power, but there are many problems to be solved to make it work normally. The first is inertia force. With the increase of rotational speed, the average speed is 7-12M/S, and the acceleration can reach about 200 g, while the rotational speed of Super Engine is twice or more than that of the conventional 1.6L. If designed according to the routine, the acceleration can reach 400 g, which is a great design challenge.

How does Super Engine do to overcome such a large inertial force? First of all, this is the advantage of a V6, V-type. For the whole vehicle, it can lower the center of gravity, and the effect is better. For me, first of all, the V-shape can decompose the inertial force into two opposite directions in the horizontal plane, and the inertial force can cancel each other out. So we only need to overcome the vertical component.

　　

Secondly, 1.6L is divided into six cylinders, and the volume of each cylinder is reduced from 0.4L to 0.266L. The mass and volume of the connecting rod can be made smaller, so the rotation speed can be improved and the inertia force can be reduced.

In addition, the moment arm of is 1/2, so the Super Engine must be as short as possible, and F1 will generally set/to 2.5, so that the inertia force will be reduced at high speed.

In addition, the system, the opening and closing of the conventional camshaft drive, can no longer meet the reliability requirements at such a high speed, plus the force attenuation, the conventional steel is completely incompetent for this work. Therefore, a high-pressure nitrogen pressure tank must be equipped separately, and the pressure release gas pushing mechanism of the pressure tank can be controlled by calculating the opening and closing time of the electromagnetic valve, so that the reciprocating motion can be carried out quickly.

Super Engine rotates at 12,000 revolutions per minute, ignites 200 times per second, and opens and closes 200 times per second. The strength and reliability requirements of these core components, as well as the accuracy of ignition design, are very high, among which titanium alloy is the best choice for material selection.

　　

It needs to be emphasized here that the increase of intake density is directly proportional to the temperature in the intercooling system of this car. The intake air volume of 4.5L is inhaled in a unit time of 1.6L According to the conventional conversion, the intake pressure will reach about 3 bar, and the temperature after vortex will be much higher than that of traditional supercharging, so it is necessary to make a special design for the intercooling system to cool the intake temperature.

Generally, the service life of F1 racing car is 1000 kilometers, over after the runway is completed, which is caused by different design concepts. F1 is to pursue the ultimate speed and win the race. If the speed is designed to be above 15,000 rpm and other performance is sacrificed to improve the speed, such as reducing the weight of all parts, its reliability will not be considered, because winning the game is more important than everything else.

The service life of AMG Project ONE is 50,000 kilometers, which is much longer than that of F1′ s1,000 kilometers. I think there are two main reasons: first, the speed is reduced to about 11,000 rpm, so the use environment of parts is much milder than that of F1; Second, the use environment of the car, F1 is basically the biggest running on the track, and the maximum potential of F1 is fully exerted. However, AMG Project ONE cannot run at full speed within its life cycle, but should have its own durable working conditions.

　　

Finally, the technology of F1 events will be decentralized to the civilian field, bringing us such a high-performance product. In my opinion, this is just a high-end souvenir for the 50th anniversary of AMG, to let the world know the technology and look forward to it. However, it didn’t achieve real civilian use, 50,000 kilometers, and the conventional car was only maintained for 3 ~ 5 times, but AMG Project ONE had to change the powertrain to continue to use. In addition, the pure electric mode only lasted for 20 kilometers, which was a bit embarrassing.

Therefore, AMG Project ONE can improve the reliability and battery technology to be truly commercialized.
